Gas grills feel more versatile once you add the right insert, basket, tray, or briquette setup. Some of these parts build charcoal flavor into a gas setup, while others improve heat zoning, ash handling, or griddle-style cooking. The right match depends on your grill model, how often you cook outdoors, and how much cleanup you want to manage after dinner.

More Details On Our Top Picks
These ceramic briquettes suit a gas grill that runs too hot in spots or throws flare-ups over fatty cuts. Ceramic, here, means a heat-storing material that spreads burner output more evenly, so your grates behave less like a hot spot map. That makes weeknight burgers and weekend chops easier to manage, though you still need to place them correctly for steady results.
Compared with the basket-style picks below, this one changes the cooking surface rather than the fuel path. That keeps the setup simpler, and the 60-pack count matters for larger grill beds or replacement cycles. The trade-off is maintenance, since ceramic pieces can collect grease and need routine cleaning.
Strong Points
- Helps smooth out uneven burner heat across the grill bed.
- Useful for cutting down flare-ups around fatty foods.
- Sixty-piece count fits larger layouts or partial replacements.
- Works as a lava-rock replacement without changing the grill itself.
Things To Consider
- Cleaning takes a little attention because grease builds on ceramic surfaces.
- Best results depend on how well your grill bed accepts briquettes.
- It improves heat distribution, but it does not transform burner output alone.

Where A Sibling Pick Shines
FlavrQ Grid 2-Ply Stainless Steel Gas Grill Insert suits you better when your goal is a true charcoal-style cooking zone instead of heat diffusion.
For 18-inch Weber kettle owners, this basket leans hard into control. The stainless-steel build is meant to organize fuel into zones, which helps you run one side hotter for searing while the other side stays milder for indirect smoking. That kind of split is especially useful on longer cooks, where the kettle turns into a small heat-management system.
Compared with the ceramic briquettes, this pick changes how fire sits in the cooker, not how the grates spread heat. That difference matters for ribs, pork shoulder, or anything that benefits from one live side and one calmer side. The honest read is that it rewards a kettle owner more than a casual gas-grill user.
Highlights
- Built for 18-inch Weber kettles, so fit is the main selling point.
- Supports two-zone cooking for searing on one side and gentler cooking on the other.
- Stainless steel construction points toward solid corrosion resistance in typical outdoor use.
- Useful for smoking sessions where fuel placement matters more than raw output.
- Gives kettle owners a clear upgrade path for more organized charcoal management.
Worth Noting
- It is model-specific, so it suits 18-inch Weber kettles rather than a wide range of grills.
- Stainless steel still needs cleaning after grease-heavy cooks.
- The larger benefit shows up on longer sessions, not quick weeknight grilling.

Who Will Love This
Kettle owners who cook brisket, ribs, or thick steaks will make the most of it.
Another Choice May Suit
Charbroil Gas2Coal Performance Series 4 Burner Charcoal Tray is a better fit for someone working with a compatible gas grill rather than a kettle.
This kit is for the gas-grill cook who wants smoke flavor without moving to a separate charcoal rig. Sugar maple chips bring a milder wood profile than heavier smoke woods, and the included stainless-steel grid gives the chips a place to sit cleanly in the burner area. In practice, that makes it a neat middle step for weeknight burgers, chicken thighs, or short smoking sessions.
Unlike the basket and briquette picks, this one leans into flavor infusion rather than heat-shaping hardware. The 2-pound bag gives you a working supply instead of a tiny sample, which matters once you start using wood more often. The trade-off is simple, you gain smoke character but not the zone control of a dedicated charcoal insert.
Reasons To Buy
- Gives gas-grill cooking a charcoal-adjacent flavor path without a full equipment change.
- Sugar maple chips suit milder smoke preferences better than harsher woods.
- Includes a stainless-steel grid, so the system is ready to place and use.
- The 2-pound bag supports repeat use for multiple cook sessions.
Softer Spots
- It adds flavor, but it does not create the same heat zones as a basket insert.
- Wood chip use asks for a little more attention during cleanup.
- Short, hot cooks may show less smoke character than longer sessions.
Core Details
Built With In Mind
Gas-grill owners who want a smoke flavor add-on without major hardware changes fit this well.
Look Elsewhere When
SnS Grills Slow ’N Sear Charcoal Basket Insert 18” Weber Kettles makes more sense for kettle cooks who need fire control instead of smoke chips.
This is the maintenance-minded pick in the group, aimed at replacing the ash-catching side of a Nexgrill-style charcoal tray system. An ash pan and tray setup matters because clean airflow and easy disposal both affect how tidy the grill stays between cooks. For owners dealing with wear, bends, or missing parts, a direct replacement often beats improvising with a loose fit.
Compared with the other items here, this one is less about flavor and more about keeping the grill functional. That makes it especially relevant for backyard setups that still perform well apart from a damaged tray section. The main limitation is obvious, it only helps the right grill family, so compatibility deserves close attention.
Upsides
- Targets a common failure point in charcoal tray systems.
- Helps restore cleaner ash handling after wear or damage.
- Useful for keeping an outdoor grill closer to original function.
- Works well for owners who prefer replacement parts over full upgrades.
Areas To Watch
- Fit matters a lot, so model matching needs careful checking.
- It solves a parts issue rather than changing cooking style.
- Replacement hardware still needs regular cleaning after use.
Details At A Glance
Whose Shelf It Belongs On
Nexgrill owners who need a replacement tray part will find the fit-focused design useful.
A Better Fit Elsewhere
onlyfire Adjustable Charcoal Tray Stainless Steel suits you better if your goal is a broader compatibility range with Weber Spirit or Genesis grills.
For kettle owners who want a flatter cooking surface, this insert shifts the grill from open grate cooking to a griddle-style setup. That matters on mornings with bacon and eggs, or evenings when smash burgers and sautéed vegetables make more sense than flame-kissed grates. The fit list is specific, which usually helps, though it also means you need to check your exact kettle model.
Compared with the Slow ’N Sear basket, this is about surface cooking rather than fire shaping. The broader 22-inch compatibility is appealing for Weber kettle households, and the flat-top format gives you more room for foods that would slip through a grate. The trade-off is that cleanup can be more involved than with simple inserts.
Best Bits
- Turns a round kettle into a griddle-style cooker.
- Useful for breakfast foods, chopped vegetables, and burger sears.
- Fits several named Weber 22-inch charcoal grill models.
- Gives you a larger continuous cooking surface than grates do.
Small Caveats
- Griddle-style cooking usually means more cleanup than open grate grilling.
- Fit depends on the exact 22-inch grill model you own.
- It changes the cooking style more than the flavor profile.

Perfect Match For
Home cooks who want a kettle-based griddle for breakfast and smash-style meals will appreciate this.
Swap It Out When
Mr. Bar-B-Q Ceramic BBQ Briquettes 60-Pack makes more sense if your priority is smoothing heat on a gas grill rather than changing a kettle into a flat top.
This insert is the most direct gas-to-charcoal conversion piece in the lineup. The 2-ply stainless-steel build suggests a sturdier structure than lighter add-ons, and the drop-in style keeps setup simple for cooks who do not want a long installation project. That simplicity helps on busy weeknights, though it also means the rest of the cooking behavior depends on your grill and fuel choice.
Compared with the briquette and smoke-chip options, this one is less about fine tuning and more about changing the fuel experience itself. That makes it appealing for someone chasing a deeper charcoal profile on a gas grill without stepping into a full second cooker. The trade-off is that the actual cooking zone is still bound by your grill’s shape and airflow.
Positives
- Turns part of a gas grill into a charcoal cooking area.
- Drop-in setup keeps installation straightforward for most grill owners.
- Two-layer stainless steel points to a sturdier feel than thinner inserts.
- Works well for cooks who want charcoal character without changing grills.
- Easy to pair with regular gas-grill routines during mixed-use cooking.
Room For Improvement
- It changes the fuel setup, but your grill geometry still shapes the outcome.
- Stainless steel needs routine cleaning after greasy cooks.
- Not the right call for someone who only wants a small flavor tweak.

Gas-grill owners who want a stronger charcoal feel without buying a separate cooker will fit this best.
Reach For A Different Pick When
SnS Grills Slow ’N Sear Charcoal Basket Insert 18” Weber Kettles is the better match for kettle users who want zoned charcoal cooking.
This tray sits in the practical middle ground between a simple replacement part and a more ambitious conversion insert. Its stainless-steel build and adjustable form make sense for Weber Spirit and Genesis owners who want a charcoal-capable tray without chasing a model-specific one-off. In everyday use, that kind of fit flexibility can save a lot of guessing.
Compared with the Grillflame replacement part, this pick is broader in scope and less tied to one damaged component. The language around saving gas points to a mixed-fuel setup, so it suits cooks who like to alternate between gas convenience and charcoal-style sessions. The catch is that any adjustable part deserves careful measurement before you commit.
What We Like
- Fits a broader set of Weber Spirit and Genesis gas grills.
- Adjustable design helps with fit flexibility.
- Stainless steel build suits regular outdoor use.
- Good match for owners who want a charcoal tray without a full grill swap.
Points To Note
- Adjustable parts still need careful measurement before purchase.
- Cleaning remains part of ownership after ash-heavy cooks.
- It is more about compatibility than a dramatic cooking-style change.

Who Should Grab It

Where A Sibling Pick Shines
Charbroil Gas2Coal Performance Series 4 Burner Charcoal Tray is the better fit for a Charbroil Performance grill owner who wants a dedicated model-specific tray.
This tray is the most straightforward match for someone already in the Charbroil Performance camp. It is built around the idea of turning a compatible gas setup into a charcoal-ready cook zone, which keeps the relationship between grill and accessory simple. That makes it feel less like an experiment and more like a purpose-fit add-on for regular outdoor cooking.
Compared with the adjustable onlyfire tray, this pick leans into a narrower ecosystem instead of broader flexibility. The upside is cleaner intent and likely easier matching for the right grill owner, while the downside is obvious, it is not meant to serve every gas grill. The honest read is that model-specific gear is often the least fussy once the compatibility line is crossed.
Best Bits
- Purpose-built for Charbroil Performance Series 4-burner setups.
- Clear gas-to-charcoal conversion role keeps the use case simple.
- Good fit for owners who already live in the Charbroil ecosystem.
- Less guesswork than broad-fit accessories.
Minor Gripes
- It serves a narrower grill family than the adjustable tray options.
- Cleaning charcoal residue is still part of ownership.
- It adds charcoal capability, but it does not change the grill into a different machine.

How To Choose The Right charcoal inserts for gas grill
Match The Insert To The Job
Start with the cooking outcome you want. Heat diffusers like ceramic briquettes are for smoothing hot spots and taming flare-ups, while baskets and trays are for organizing charcoal into zones or replacing a worn part. Smoke-chip kits sit in a different lane, since they add aroma more than they reshape the whole fire path.
That distinction matters in a busy kitchen or backyard line-up because the wrong insert can feel underwhelming fast. A steakhouse-style sear needs a different structure than a Sunday pork shoulder. The best match starts with the job, not the label.
Check Fit Before Flavor
Size and compatibility come first with this category. A basket made for an 18-inch Weber kettle will not help a Charbroil Performance owner, and a replacement ash pan only works when the original tray layout matches. Measure twice, then compare the listed grill family, tray shape, and install method.
Broad-fit options can be useful, but they usually ask for more careful checking. Model-specific gear often feels cleaner once installed, though it narrows your pool of choices. That trade-off is normal, not a flaw.
Think About Cleanup And Storage
Charcoal hardware adds ash, grease, or residue somewhere in the process. Stainless steel tends to clean more easily than porous materials, while ceramic parts can need a gentler hand. A griddle insert usually asks for more post-cook work than a simple tray or basket.
Storage matters too, especially in smaller garages or patio cabinets. Flat parts stack neatly, but larger baskets or multi-piece sets may need a dedicated shelf. The more complex the insert, the more likely you are to notice it after the meal.
Pick For Your Cooking Style
Frequent sear-and-smoke cooks benefit from two-zone baskets. Weeknight grillers usually prefer drop-in simplicity, while families who cook breakfast outdoors may get more use from a flat-top insert. If you mostly want better heat behavior, briquettes are the quiet utility choice.
That’s the real filter: charcoal flavor, heat shaping, replacement function, or surface expansion. One accessory rarely does all four well. Choose the one that matches the way you actually cook.
Things Worth Knowing First
Common Shopping Slip Ups
Many mismatches happen because the grill model gets assumed rather than checked. A 22-inch kettle accessory, a Nexgrill replacement part, and a universal-looking tray are not interchangeable. Your grill’s exact family name usually tells you more than the product photo.
Another common miss is buying a flavor accessory when you wanted a heat-management piece. Smoke chips, briquettes, and charcoal baskets solve different problems. Matching the part to the cooking goal saves frustration later.
What The Higher Tier Buys
Better materials often mean better fit, steadier shape, and less wobble after repeated use. Stainless steel trays and two-ply inserts usually cost more because they are built to survive hot cycles and outdoor storage with less drama. That kind of construction makes sense for frequent grill use.
The upgrade only pays off when you use the accessory often enough to notice the difference. Occasional cooks may be fine with a simpler piece, while regular weekend grillers usually appreciate the sturdier build. Paying more only makes sense when the part becomes part of your routine.
Frequently Asked Questions
What does a charcoal insert do on a gas grill?
It changes how the grill handles heat, fuel, or both, depending on the design. Some pieces add charcoal-style cooking, while others smooth hot spots or help with ash control.
Do these inserts fit every gas grill?
No, fit varies a lot by brand, burner layout, and cooking area size. Model-specific parts are often the safest path.
Can you use charcoal baskets and briquettes for the same job?
Not really, since they solve different problems. Baskets organize charcoal, while briquettes help spread heat across the grill bed.
Are stainless steel inserts easier to maintain?
They usually clean up more easily than porous or coated materials. Grease and ash still need regular attention after use.
Which option suits someone who wants more smoke flavor?
A smoke-chip kit is the most direct fit for that goal. It adds aroma without changing the grill into a dedicated charcoal cooker.
Closing Thoughts
The right insert turns a familiar gas grill into a more flexible cooking tool without forcing you into a full equipment change. Some of these picks tune heat, some manage charcoal, and some add a flatter surface for different kinds of meals. Start with your grill model, then decide whether you want flavor, control, repair, or extra cooking space. That order keeps the choice sensible, and it usually leads to a setup you’ll actually use.
